Frequently Asked Questions

What type of installations is this 4 mm² cable recommended for?

This cable is specifically designed for fixed indoor installations, both in homes and in offices and commercial premises. It is perfect for circuits for washing machines, dishwashers, electric water heaters, ovens, and other power outlets that require a cross-section of 4 mm² according to the Low Voltage Electrotechnical Regulations (REBT).

What does it mean for the cable to be halogen-free?

This means its insulation does not contain halogenated chemical elements such as fluorine, chlorine, bromine, or iodine. In the event of a fire, this prevents the release of toxic gases and acids that damage electronic equipment and endanger human health, as well as drastically reducing the amount of smoke generated.

Can it be installed directly buried in the wall?

This flexible wire is designed to be installed under protective conduit, either embedded in walls or on the surface. Direct installation without conduit or direct burial is not recommended.
